问题：
javascript - 关于一个element table合并列的技术需求疑问？
景恩
我想合并三个圈出来的地方，
后端返回的数据结构是2个，我把它扁平化成4个了并且绑定了，现在想合并单元格，但是猪脑不够用了，而且拆了之后它那个switch怎么绑定回父级的row也没想好。有没有巨佬帮一下我，非常感谢
<template> <el-table :data="flattenedData" :span-method="objectSpanMethod" border> <el-table-column type="selection" align="center" :reserve-selection="true" fixed width="50"> </el-table-column> <el-table-column prop="name" label="商品信息" width="200"> <template slot-scope="scope"> <span>{{ scope.row.name }}</span> </template> </el-table-column> <el-table-column prop="agency.name" label="适用机构" width="120"> <template slot-scope="scope"> <span>{{ scope.row.agency.name }}</span> </template> </el-table-column> <el-table-column label="分佣比例" align="center" prop="agency.marketPrice" /> <el-table-column label="是否首页推荐" align="center" min-width="80"> <template slot-scope="scope"> <el-switch v-model="scope.row.bili" active-value="1" inactive-value="0"></el-switch> </template> </el-table-column> </el-table></template><script>export default { data() { return { rawData: [ { id:1, name: '入职体检A', bili: 1, agencies: [ { name: '博爱医院', marketPrice: 100.00, costPrice: 30.00, platformPrice: 80.00, totalProfit: 120.00, platformShare: 80, platformProfit: 72.00, businessShare: 20, businessProfit: 18.00, rowspan: 3 }, { name: '天美体检', marketPrice: 200.00, costPrice: 40.00, platformPrice: 150.00, totalProfit: 110.00, platformShare: 80, platformProfit: 72.00, businessShare: 20, businessProfit: 18.00, rowspan: 0 }, { name: '美年体检', marketPrice: 300.00, costPrice: 50.00, platformPrice: 100.00, totalProfit: 100.00, platformShare: 80, platformProfit: 72.00, businessShare: 20, businessProfit: 18.00, rowspan: 0 } ] }, { id:2, name: '入职体检B', bili: 0, agencies: [ { name: '博爱医院', marketPrice: 200.00, costPrice: 100.00, platformPrice: 150.00, totalProfit: 90.00, platformShare: 80, platformProfit: 72.00, businessShare: 20, businessProfit: 18.00, rowspan: 1 } ] } ], flattenedData: [] }; }, created() { this.flattenData(); }, methods: { flattenData() { this.flattenedData = []; this.rawData.forEach(product => { product.agencies.forEach(agency => { this.flattenedData.push({ name: product.name, agency: agency, bili: product.bili }); }); }); console.log(this.flattenedData) } }};</script><style scoped>.el-table .cell { display: flex; align-items: center;}</style>共有3个答案

思路
既然你数据都做了合并处理，就按你数据整。你页面跟你数据字段还不一样agency跟agencies能一样么，太坑了。大致思路就是循环展示，“适用机构”与“分佣比例”其实就是一个for循环。最后推荐scope.row.bili没毛病，需要一个@change接受触发事件，给后台。
重点
兄弟你那个bili一定给个字符串型。你页面是字符串，数据是Number型。Json能用字符串一律用字符串，除非是前端需要计算金额才用number型，其他仅仅展示一律字符串。
代码

不要合并单元格，就一行写，有多个子项的时候自己模拟单元格下边框

a）是否有一种方法来确保AltBeacon广告是唯一的。从某种意义上说，其他人不会错误地在他们的信标中使用相同的UUID，主要和次要ID。因为如果发生这种情况，我们的应用程序有可能识别另一家公司的信标并出现故障，反之亦然。 所以，我想知道目前在AltBeacon规范和库本身中是否有任何解决方案（变通方法）？还是他们在排队？我不确定，这是否是可以在库级别本身完成的事情，或者Android级别或者可能
